first large scale spl system

I am just getting back into car audio after a long 12 years off. I was an installer, IASCA judge and a Member of Rockford's Team America in the early years. I am trying to design my first large scale SPL vehicle. So far I am considering Sixteen (16) 12" 4OHM DVC subs on 2 13000 watt 4OHM High Current competition amps. I wanted to ask someone to double check my math. (8) - 4 Ohm DVC Subs Wired (series / parallel) = 2 ohm load Voice coils wired in series, speakers wired in parallel. Dual 2 ohm load Voice Coils wired in parallel should equal a 4 Ohm MONO load Total. All suggestions are appreciated. I can't believe how easily you lose it if you don't use it. ;) Thanks.kitbolton

https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=4&I=42#results I see two ways to reach a 4 ohm load using (8) 4ohm DVC woofers. The calculator above only does up to four woofers, but you can combine two sets of four into a set of eight, and so forth. Have fun with your build. -JMalcom: "This is the captain.

You have 8 subs on each amplifier.   Each sub is series wired to 8 ohms.  Use the parallel calculator to find that 8 X 8 ohm subs will net a 1 ohm impedance.  So each of your amps should work with a 1 ohm load.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
